Description

超声波诊断装置、发送和接收超声波的方法、以及用于发送和接收超声波的程序 The ultrasonic diagnostic apparatus, an ultrasonic wave transmitting and receiving method, and a program for transmitting and receiving ultrasonic waves

技术领域 FIELD

[0001] 本发明涉及使用具有多个超声波换能器的超声波探头来诊断对象(例如,人体)内部的超声波诊断装置;涉及发送和接收超声波的方法,该方法发送和接收从超声波探头至对象的超声波;涉及用于发送和接收超声波的程序,该程序使得计算机执行发送和接收超声波的方法的多个步骤,即,发送和接收超声波的多个步骤;以及涉及在其中记录了用于发送和接收超声波的程序的计算机可读记录介质。 [0001] The present invention relates to a transducer of an ultrasonic probe to the diagnostic object (e.g., human body) inside of the ultrasonic diagnostic apparatus having a plurality of ultrasonic waves; relates to a method for transmitting and receiving an ultrasonic wave, the method of transmitting and receiving the object from the ultrasonic probe to ultrasound; relates to a program for transmitting and receiving an ultrasonic wave, the program causing a computer to perform a plurality of steps of the method of transmitting and receiving an ultrasonic wave, i.e., a plurality of steps of transmitting and receiving ultrasonic waves; recorded therein and to send and receive computer readable program ultrasound recording medium. 具体地,本发明涉及允许穿刺术(paracentesis)等的技术,在该技术中,在观看超声波图像时将穿刺针插入对象中。 In particular, the present invention relates to permit puncture (paracentesis) technique or the like, in this technique, while viewing the ultrasonic image of the puncture needle is inserted into a subject.

背景技术 Background technique

[0002] 通过集成多个超声波换能器(振动器)来形成在超声波诊断装置中使用的超声波振动器。 [0002] used to form the ultrasonic vibrator in the ultrasonic diagnostic apparatus by integrating a plurality of ultrasonic transducer (vibrator). 在发送和接收超声波时,在多个超声波换能器中的每个超声波换能器上设置发送开口和接收开口,以及针对每个超声波换能器,适当地控制每个超声波换能器的发送开口的发送输出与接收开口的接收输出中每个的延迟时间(延迟量)。 When transmitting and receiving the ultrasonic, transducers in each of the plurality of ultrasonic transducer is provided on the ultrasonic transmitting and receiving aperture opening, and for each of the ultrasonic transducers, the ultrasonic transmitter appropriately controlling each transducer receiving a transmission output and the output opening of the receiving opening in each of the delay time (delay amount). 分别合成超声波发送波束和超声波接收波束,以获得超声波接收图像数据。 Were synthesized ultrasonic beam transmitted and received ultrasonic wave beams, to obtain the ultrasonic image data received.

[0003] 超声波诊断装置是已知的,其具有以下结构(穿刺适配器):可以将穿刺针安装到超声波探头,使得可以使用专用穿刺针来容易地执行在作为测量目标的对象中特定位置上的活组织检查(biopsy)。 [0003] The ultrasonic diagnostic apparatus is known, which has the following structure (puncture adapter): puncture needle may be mounted to the ultrasound probe, such that the puncture needle can be dedicated to a specific location easily performed as a measurement target object on biopsy (biopsy). 在该装置中,在显示器上显示插入穿刺针时的导向(guideline)。 In this apparatus, the display guide (Guideline) when inserting the puncture needle on a display. 如果在根据导向将穿刺针插入对象时,使用超声波探头来操作超声波诊断装置,操作者可以同时确认对象中的图像和穿刺针在显示器上的运动,由此执行安全的穿刺术(活组织检查、引流等等)。 If in the guide needle when inserting an object using an ultrasonic probe to operate the ultrasonic diagnostic apparatus, an operator can confirm the image while moving object and the puncture needle on a display, thereby performing a safe puncture (biopsy, drainage, etc.).

[0004] 然而,在相关技术的超声波诊断装置中,存在着以下问题:取决于穿刺针的进入角度,来自穿刺针的回波信号的强度较弱,并且在显示器上难以查看穿刺针的图像。 [0004] However, in the ultrasonic diagnostic apparatus of the related art, there is the following problem: depending on the angle of entry of the needle, the intensity of the echo signal from the puncture needle is weak, and it is difficult to see the image on a display of the puncture needle. 作为解决该问题的方法,已知对穿刺针的尖端表面进行粗糙处理(粗糙化)的技术。 As a method for solving this problem, it is known to the tip surface of the puncture needle technology roughening treatment (roughening) of. 然而,该技术具有以下问题:未充分加强来自穿刺针的除针头外部分的回波信号,并且未充分加强回波信号本身。 However, this technique has the following problems: the needle is not sufficiently strengthen the outer portion of the echo signal from the other puncture needle, and the echo signal itself is not sufficiently strengthened.

[0005] 为此,JP 9-28708A描述了以下技术:当将穿刺针插入对象中时,将超声波扫描波束的发送波束方向调整为相对于穿刺针的进入路径实质成直角,以及控制每个超声波换能器的输出的延迟量,以使得每个扫描波束的发送波束焦点位置在穿刺针的位置附近。 [0005] To this end, JP 9-28708 describes a technique: when the puncture needle is inserted into a subject, to adjust the transmission direction of the ultrasonic beam scanning beam with respect to the puncture needle into the path of substantial right angle, and controlling each of the ultrasonic the delay amount of the output transducer, so that the transmission beam of each scanning beam focus position near the position where the puncture needle.

发明内容 SUMMARY

[0006] 另一方面,在JP 9-28708A中描述的技术中,使用超声波扫描波束的发送波束的方向和焦点控制,可以加强目标线路(例如,穿刺针进入对象的线路)的超声回波信号,然而存在的问题是使得发送和接收控制变得显著的复杂。 [0006] On the other hand, in the technique described in JP 9-28708A, the use of ultrasonic scanning beam transmission beam direction and focus control can be enhanced ultrasound echo signal of the target line (e.g., needle into the subject line) However, there is a problem such that transmission and reception control becomes significant complexity.

[0007] 在JP 9-28708A中描述的技术中,没有将超声波扫描波束的接收波束的方向性等充分考虑在内,并且存在的问题是提高来自穿刺针的回波信号的强度的效果不够。 [0007] In the technique described in JP 9-28708A, the ultrasonic beam is not received scanning beam directional property sufficiently into account, there is a problem and the effect of improving the strength of an echo signal from the puncture needle is not enough. 例如,在JP 9-28708A中描述的技术中,存在以下问题,如果穿刺针的插入角度增加,在接收时,发送波束的镜面反射分量会在多个超声波换能器上设置的接收开口之外,以及不能充分接收到来自穿刺针的回波信号,由此导致回波信号的强度被削弱。 For example, in the technique described in JP 9-28708A, the following problem, if the insertion angle of the receiving opening beyond the puncture needle increases, when receiving, the specular reflection component of the transmission beam is set on the plurality of ultrasound transducers , and can not be sufficiently received echo signals from the puncture needle, thereby causing the intensity of the echo signal is attenuated.

[0008] 此外,还存在以下问题:由于超声波扫描波束的发送是相对于对象表面而倾斜的转向发送(steer transmission),即使在可以提高穿刺针的可见度的情况下,除穿刺针之外的图像的质量会恶化。 [0008] In addition, there is a problem: since the transmission ultrasonic scanning beam relative to the object surface inclined steering transmission (Steer Transmission), even in the case can be improved puncture needle of a visible image other than the puncture needle the quality will deteriorate.

[0009] 在JP 9-28708A中描述的技术中,由于没有直接存储来自穿刺针的超声回波信号,存在以下问题:在接收后进行图像处理时,可能未提高来自穿刺针的超声回波信号的强度,且从而未提高穿刺针的可见度。 [0009] In the technique described in JP 9-28708A, since no ultrasonic echo signal from the direct memory puncture needle, the following problems: When the image processing after reception, may not improve the echo signals from the ultrasonic puncture needle strength, and so does not improve the visibility of the puncture needle.

[0010] 考虑到上述情况而完成了本发明,且本发明的目标是提供能够提高来自穿刺针的超声回波信号的强度并提高穿刺针的可见度的超声波诊断装置、发送和接收超声波的方法、用于发送和接收超声波的程序以及记录介质。 [0010] In view of the above circumstances the present invention, and the object of the present invention is capable of improving the strength of the ultrasound echo signal from the puncture needle and improved ultrasonic diagnostic apparatus visibility of the puncture needle, transmitting and receiving method of ultrasonic waves, procedures for transmitting and receiving an ultrasonic wave and a recording medium.

[0075] 图3是示出了相关技术的超声波探头中超声波的发送波和反射波之间的几何关系的示意图。 [0075] FIG. 3 is a schematic view illustrating the geometric relationship between the ultrasonic probe related art ultrasonic wave transmitted and reflected waves. 为了描述的简单,示出了在对象BI的本体表面没有折射的情况(对后续图也同样成立)。 For simplicity of the description, in the case illustrated the main body surface of the subject no refractive BI (the same is true for the following figures).

[0076] 穿刺针由金属形成,并且在超声波阻抗方面与周围的对象组织明显不同。 [0076] The puncture needle is formed of metal, and in terms of the object ultrasound impedance significantly different from surrounding tissue. 由于该原因,认为在超声波图像中明显地获得了穿刺针的图像。 For this reason, in the ultrasound image that is obtained clearly image the puncture needle. 然而,实际上如果捕获到超声波图像,穿刺针没有形成与其他组织区分开的图像。 However, actually, if an ultrasound image is captured, the puncture needle does not form separate areas of the image with other organizations. 相反,存在着很多间歇性地查看到穿刺针的情况。 In contrast, there are many cases intermittently view puncture needle. 相应地,发明人进行了仔细的研究,并得到以下发现。 Accordingly, the inventor was carefully studied and the following findings.

[0077] S卩,如图3所示,如果从探头12的多个超声波换能器13向对象BI发送的超声波进入紧靠穿刺针NI的对象BI,并由穿刺针NI进行了镜面反射,则存在反射波在探头12的接收范围之外的情況。 [0077] S Jie, shown in Figure 3, if the ultrasonic transducers from the plurality of the ultrasonic probe 12 to the subject 13 BI BI transmitted into the subject close to the puncture needle NI, NI needle carried by specular reflection, where the reflected waves outside the reception range of the probe 12 is present. 例如,从Pl发送的超声波以图3中的參考符号“a”所指示的入射波方向进入对象BI,并在镜面反射中由穿刺针NI在图3中由參考符号“b”指示的方向上反射,而在P1'处接收到具有由图3中的參考符号“I”指示的強度分布的反射波。 For example, Pl incident wave from the ultrasonic transmission direction in FIG. 3 at reference symbol "a" indicated by the BI into the subject, and the direction of specular reflection by the puncture needle NI indicated in Figure 3 by reference symbol "b" is reflection, the reflected wave is received intensity distribution indicated by the reference symbols in FIG. 3 "I" having at P1 'at. 对象组织所反射的普通超声回波信号在由图3中的參考符号“c”指示的方向上行进,并在Pl处接收至IJ。 Normal ultrasonic echo signal reflected by the object tissue in a direction indicated by reference numerals in FIG. 3 "c" to travel to and receives at IJ at Pl.

[0078] 然而,从P2发送的超声波被穿刺针NI所镜面反射,到达P2',并因此在探头12的接收范围之外。 [0078] However, the puncture needle from the ultrasonic NI P2 sends the specularly reflected reaches P2 ', and thus outside the reception range of the probe 12. 据此将描述以下现象:如果反射波的部分或整体逃离并且没有到达探头12,难以在超声波图像中查看到穿刺针NI的图像。 According to this phenomenon will be described in the following: If a part or the whole of the reflected wave does not reach the probe 12 and the escape, it is difficult to view the image of the puncture needle in the ultrasonic image NI.

[0079] 一般而言,假设在将器官的组织假设为对象的超声波诊断技术中,接收到当超声波被器官的组织所反射时所获得的普通超声回波信号(例如,具有点反射分量),并由该超声回波信号形成图像。 [0079] In general, it is assumed in the organ tissue is assumed to be the ultrasonic diagnostic art object, the normal ultrasonic echo signal received when the reflected ultrasonic wave is obtained organ tissue (e.g., having a reflection point component), the ultrasonic echo signal formed by the image. 然而,一般而言,穿刺针是金属体,并且其表面是光滑的。 However, in general, the puncture needle is a metal body, and its surface is smooth. 在这种情况下,预见超声波在穿刺针表面的反射特性与器官的组织明显不同,并且镜面反射很突出。 In this case, the reflection characteristic foreseen ultrasonic puncture needle and the surface is significantly different tissues and organs, and the specular reflection is very prominent. 由于从超声波探头的多个超声波换能器发射的超声波在穿刺针的光滑表面上进行了镜面反射,在相关技术的超声波诊断装置中,当使用在作为对象的器官的本体表面布置的超声波探头接收在其中叠加了从器官组织反射的普通超声回波信号(也称为点反射分量)和穿刺针的表面镜面反射的镜面反射分量的信号,以同时收集与器官组织有关的信息和与穿刺针的尖端部分有关的信息吋,难以将穿刺针的尖端部分作为在超声波图像数据上的图像稳定地观察到。 Because the plurality of ultrasonic transducers of the ultrasonic probe of the ultrasonic wave emitting specular reflection on a smooth surface of the puncture needle, the ultrasonic diagnostic apparatus in the related art, when using the received ultrasonic probe body surface of the organ as the object of the arrangement which is superimposed on ordinary ultrasonic echo signal reflected from the organ tissue (also referred to as a reflection point component) signal and the specular component surface reflected specular puncture needle, to simultaneously collect information about the organ tissues and a puncture needle information relating inch tip portion, the tip portion of the puncture needle is difficult to stably observe an image on the ultrasonic image data.

[0080] 相应地,关于可以捕捉到到达图3中P2'的反射波的超声波诊断装置,发明人获得了以下发现。 The ultrasonic diagnostic apparatus of a reflected wave [0080] Accordingly, with respect to FIG. 3 can capture the arrival P2 ', the inventors obtained the following findings. 首先,第一发现在干与相关技术相比具有长的接收范围的超声波探头,具体地,与相关技术相比,制造了以下超声波探头:其具有阵列部分,在阵列部分中布置了超声波换能器。 First, the first found in the dry compared to the related art ultrasonic probe having a long reception range, in particular, as compared with the related art, an ultrasonic probe manufactured following: an array having a portion disposed in the ultrasonic transducer array portion device. 然而,这是不够的。 However, this is not enough. 例如,虽然具有256个超声波换能器的超声波探头具有相对长的阵列部分,在发送和接收超声波的普通方法中,存在着很多如下情况:关于单个发送和接收,仅使用64个超声波换能器(对应于256的1/4)来设置64个通道,或者可设置更短数目的通道。 For example, although the ultrasonic probe having 256 ultrasonic transducers having a relatively long portions of the array, the common method of transmitting and receiving an ultrasonic wave, there are a lot of the following: on a single transmission and reception, only the 64 ultrasonic transducers (corresponding to 1/4 of 256) to set the channels 64, or may be set shorter number of channels.

[0081] 相应地,固有的问题不是指阵列部分的长度,而是指在超声波探头的多个超声波换能器上设置的接收开ロ是否覆盖了超声波被预测要到达的范围,该超声波从超声波探头的多个超声波换能器上设置的发送开ロ发送,并在穿刺针的表面镜面反射。 [0081] Accordingly, the inherent problem is not part means the length of the array, but to the receiving opening ro provided on a plurality of ultrasonic transducer of the ultrasonic probe whether the coverage range of the ultrasonic predicted to be reached, the ultrasonic wave from the ultrasonic ro transmission opening provided on a plurality of transmission ultrasonic transducer probe, and the specular reflection of the surface of the puncture needle. 相应地,发明人的第二发现在于预测镜面反射波要到达的范围,以及基于预测结果将超声波探头的接收开ロ设置为与发送开ロ不同,例如,大于发送开ロ,以使得超声波探头可以覆盖(接收)镜面反射波。 Accordingly, the second finding of the invention is that the prediction range specularly reflected wave to arrive, and based on the prediction result of the received ultrasound probe set as the transmission start and open ro ro different, e.g., greater than ro transmission opening, so that the ultrasonic probe can be cover (receiving) specularly reflected waves. 发送开口和接收开ロ是在多个超声波换能器上设置的,并且意味着用于接收的超声波换能器的位置和超声波换能器的数目(通道数)。 Transmission and reception on ro openings are provided on a plurality of ultrasonic transducers, and the number (number of channels) means for receiving ultrasonic position transducer and ultrasonic transducer.

[0082] 为了仅获得穿刺针的图像,仅考虑来自穿刺针的镜面反射波(也称为镜面反射分量)。 [0082] In order to obtain only the image of the puncture needle, considering only the specularly reflected wave from the puncture needle (also referred to as a specular component). 首先,由于穿刺术是在存在穿刺术的目标(对象组织)的情况下将穿刺针向对象插入的动作,重要的是获得穿刺术的目标以及周围组织的图像。 First, since the puncture target in the presence of a puncture (target tissue) will be inserted into the puncture needle to a subject an operation, an image is important to obtain the target and the surrounding tissue puncture. 在这种情况下,对于超声波诊断装置来说,不仅覆盖穿刺针的镜面反射分量,而且充分接收从普通对象组织反射的普通超声回波信号,这都是必要的。 In this case, the ultrasonic diagnostic apparatus, not only covers the puncture needle of the specular component, and sufficiently receive ordinary ultrasonic echo signal reflected from the target normal tissue, it is necessary.

[0083] 图4是示出了根据本发明的实施例发送和接收超声波的方法的基本概念的示意图,该方法是由本实施例的超声波诊断装置执行的。 [0083] FIG. 4 is a schematic diagram showing the basic concept of a method of transmitting and receiving an ultrasonic wave according to embodiments of the present invention, the process is an ultrasonic diagnostic apparatus of the present embodiment is performed.

[0084] 图4示出了探头12的发送开ロTl和接收开ロR1,以及与相关技术的超声波诊断装置类似,用于接收从对象组织等反射的普通超声回波信号(点反射分量)的接收开ロR2与发送开ロTl相一致。 [0084] FIG. 4 shows a transmitting probe 12 and the opening ro Tl similar ultrasonic diagnostic apparatus receiving opening ro R1, and the related art, for receiving ultrasonic echo signals reflected from normal tissues like object (reflection point component) R2 receiving opening ro ro Tl transmission opening coincide. 同时,在图4中,用于从穿刺针NI接收镜面反射分量的接收开ロR3与发送开ロTl不一致,井向右扩展。 Meanwhile, in FIG. 4, a receiver for receiving specular component apart from the puncture needle NI ro ro Tl R3 inconsistent transmission opening, extended well to the right. 更具体地,设置R3以包括超声波换能器13中的以下超声波换能器:位于与将穿刺针NI插入对象BI的插入位置相对于发送开ロTl的相对侧处,以使得接收开ロR3被设置在位于适当位置中的两个或更多超声波换能器13上,以接收由穿刺针N反射的超声波束的镜面反射分量。 More specifically, R3 is set to 13 in the ultrasonic wave comprises an ultrasonic transducer transducer: located in the puncture needle NI inserted objects BI insertion position with respect to the transmission opening ro opposite side of Tl, so that the receiving opening ro R3 two are disposed in place of one or more ultrasonic transducers 13, for receiving the ultrasound beam reflected by the puncture needle N specular component.

[0085] 在本实施例的发送和接收超声波的方法中,在其中组合了用于普通超声回波信号的接收开ロR2和用于镜面反射分量的接收开ロR3的合成开ロ是接收开ロRl。 [0085] In the method of transmitting and receiving an ultrasonic wave according to the present embodiment, in which the combination of R2 and reception on ro ro opening for receiving the specular component for general Syntheses ro ultrasonic echo signal is received to open R3 ro Rl. 从而,与本领域中的已知类型相比,接收开ロRl向着与穿刺针NI进入对象BI的插入位置相对于发送开ロTl的相对侧扩展了更多。 Accordingly, as compared with known types in the art, Rl receiving opening ro toward the puncture needle into the target BI NI insertion position relative to the transmission side opening extended Tl ro more. 通过这种方式,装置本体14使用根据穿刺针的镜面反射分量来改变探头12的接收开ロRl的位置和宽度(通道数目)的模式。 In this way, the use of the apparatus body 14 to change the position and width of the receiving opening ro Rl is (number of channels) of the probe 12 according to the mode of the specular reflection component puncture needle.

[0086] 虽然实质上只有普通超声回波信号到达用于普通超声回波信号的接收开ロR2,将显而易见的是,镜面反射分量和普通超声回波信号到达用于镜面反射分量的接收开ロR3。 [0086] Although only substantially normal ultrasonic echo signal reaches the ultrasonic echo signal for normal reception opening ro R2, it will be apparent that the specular reflection component and the ultrasonic echo signal reaches the normal specular component for receiving open ro R3.

[0087] 图5是示出了在本实施例中对在穿刺针上镜面反射的超声波到达的范围进行预测的方法示例的示意图。 [0087] FIG. 5 is a schematic diagram showing an example method embodiment of the puncture needle in the range of specularly reflected ultrasonic waves arriving in the prediction of the present embodiment. [0088] 如果穿刺针NI进入对象BI的插入角度是0 1,传输发送波束的中心位置是P11,在中心位置Pll处从对象BI的表面到穿刺针NI的深度是D1,当在距离超声波发送波束的中心位置Pll的深度Dl处,在穿刺针NI上发生镜面反射之后,超声波换能器接收到反射波的点是PlT,以及从超声波发送波束的中心位置Pll到穿刺针的插入位置之间的距离是W1,通过表达式(I)来计算反射波返回的点Pir与发送波束的中心点Pii之间的距离Li。 [0088] If the needle NI entry target BI insertion angle is 01, the transmission of a transmission beam center position P11, the center position Pll is that D1 from the surface of the object BI to a depth of the puncture needle NI when transmitted from the ultrasonic Pll depth Dl at the central position of the beam after specular reflection occurs on the NI puncture needle, the ultrasound transducer receives the point of the reflected signal PLT, and the center position between the transmission beams from the ultrasonic Pll puncture needle to the insertion position the distance W1, calculates the distance Li between the centers of the reflected wave returns to the Pir point Pii transmission beam by the expression (I).

[0089] L1 = D1 tan 2 0 [0089] L1 = D1 tan 2 0

[0090] = W1 tan 0 :tan2 0 x ... (I) [0090] = W1 tan 0: tan2 0 x ... (I)

[0091] 相应地,优选地考虑反射波返回的点pit,以确定接收开ロ的宽度。 [0091] Accordingly, it is preferable to consider reflected waves return point pit to determine the width of the receiving opening of ro. 例如,在不考虑穿刺针NI的普通发送和接收中,将发送开ロTl和接收开ロR2(參见图4)设置在64个元素中,以及当基于穿刺针NI的反射波来接收回波信号吋,向反射波的到达点PU'扩展接收开ロRl (參见图4),以将接收开ロ的数目设置为例如最大数目,即96个元素。 For example, in the conventional transmission and reception irrespective of the puncture needle NI, transmitting and receiving opening open ro ro Tl R2 (see FIG. 4) provided in the elements 64, and when the puncture needle based on the reflected waves received back to NI inch wave signal, to the reflected wave reaches the point PU 'extended receiving open ro Rl (see FIG. 4), to the number of the receiving opening is set, for example ro maximum number, i.e. 96 elements. 具体地,当在发送开ロ的最右端形成超声波发送波束时,超声波发送波束的反射超声波返回的最右端处的点是临界点,以且在最佳状态下,接收开ロ覆盖该点。 Specifically, when forming an ultrasonic transmission beam transmitted at the far right of open ro, the point at the rightmost end of an ultrasonic transmission beam reflected ultrasonic wave returns critical point to and in the best condition, covers the receiving opening ro point.

[0092] 当有必要考虑到对象BI的本体表面或对象BI内部的折射的影响时,优选根据Snell定律执行计算。 [0092] When it is necessary to consider the influence of refraction of the body surface of the object or inside the object BI BI, preferably performed is calculated according to Snell's law.

[0093] 在镜面反射分量计算器42中,产生确定接收开ロ的宽度所必需的信息(例如,在上述的示例中,反射波返回的点Pir的位置信息),以作为镜面反射分量信息。 [0093] In the specular component calculator 42, determines whether the received information is generated (e.g., in the above example, the position information of the reflected wave is returned to the point Pir) ro opening width required, as a specular reflection component information. 信号处理器44基于该信息确定对来自接收数据存储単元40的接收数据进行处理的方法,以及系统控制器32控制复用器36中的切换方法。 The method of the signal processor 44 determines, based on the information received from the meta data storage radiolabeling the received data 40 is processed, and a method of switching the system controller 36 controls the multiplexer 32.

[0094] 从系统控制器32向镜面反射分量计算器42提供穿刺针NI进入超声波换能器阵列的插入角度9 1,以作为穿刺适配器信息。 [0094] The system controller 32 provides the puncture needle NI specular component to the calculator 42 from the insertion angle of the ultrasound transducer array 91, as the puncture adapter information. 如图6中所示,当穿刺适配器20安装到探头12时,可以在显示器18上显示用来引导穿刺针NI的穿刺导向G,且对于技术员,可以将穿刺针NI的插入角度0 I作为穿刺导向G和对象BI的表面之间的角度。 As shown in FIG. 6, when the puncture adapter 20 is mounted to the probe 12 may be displayed for guiding a puncture needle guide G on the display 18 NI, and for the technician can puncture needle insertion angle 0 I NI puncturing as the angle between the guide surface of the object G and the BI.

[0095] 虽然未示出,可以向装置本体14単独提供穿刺针检测器,以使得基于穿刺针的位置信息来确定插入角度,穿刺针的位置信息由穿刺针检测器基于超声波图像自动识别,并从穿刺针检测器输出。 [0095] Although not shown, may be provided needle detector apparatus body 14 radiolabeling alone, so that the determined angle of insertion based on the positional information of the puncture needle, the positional information of the puncture needle is automatically identified by the puncture needle detector based on the ultrasound image, and output from the puncture needle detector.

[0096] 如上所述,在根据本发明的实施例I的发送和接收超声波的超声波诊断装置和方法中,基于穿刺针和超声波探头之间的位置关系来确定接收开ロ的宽度(通道数目),以及针对在对应接收开口中获得的接收信号来执行波束成形。 [0096] As described above, in the embodiment of the present invention I and an ultrasonic diagnostic apparatus transmitting and receiving an ultrasonic wave, the positional relationship between the puncture needle and the ultrasound probe is determined based on the width (number of channels) in accordance with the received opening ro , and the received signal obtained in a corresponding receiving opening to perform beamforming. 相应地,由于可能提高包括所插入的穿刺针在内的超声波图像的分辨率,穿刺针的可见度也提高了。 Accordingly, it is possible to improve the resolution since the insertion puncture needle including an ultrasound image including, visibility of the puncture needle is also improved. 对穿刺针和超声波探头之间的位置关系进行表示的信息中最重要的參数是所发送的超声波的行进方向与穿刺针之间的角度,以及,穿刺针的插入角度。 The most important parameter information on the positional relationship between the puncture needle and the ultrasound probe represents the angle between the traveling direction of the ultrasound transmitted with the puncture needle, and a puncture needle insertion angle.

[0097] 在本实施例中描述了这样的模式:将接收开ロ相比于相关技术中的接收开ロ加以扩展,以接收镜面反射分量和普通的超声回波信号(点反射分量)。 [0097] Examples of such a mode is described in the present embodiment: the receiving opening receives ro compared to the related art open ro be expanded to receive the specular reflection component and the ordinary ultrasonic echo signal (reflection point component). 然而,例如在没有向普通的超声回波信号给出权重时,可以使用基于镜面反射分量信息来改变接收开ロ的位置的模式。 However, for example, when not given the conventional ultrasonic echo signal weighting can be used to change the position of the receiving opening ro based on the specular reflection component information mode.

[0098] 虽然在本实施例中,已描述了改变接收开ロ的宽度的情况(例如,从64个元素到96个元素的改变),然而可以改变接收开ロ的位置,以使得将发送波束方向上的中心位置以及来自穿刺针的镜面反射分量的到达位置包含在接收开ロ中。 [0098] In the present embodiment, description has been changed reception conditions widths apart ro (e.g., change from 64 elements to 96 elements), but may be varied received open ro position, so that the transmission beam and the center position in the direction of arrival from the position of the specular component included in the received puncture needle in the opening ro. 可以分别设置用于从发送波束方向接收超声回波的接收开ロ以及针对于来自穿刺针的镜面反射分量的到达位置的接收开ロ。 It may be provided for receiving the open ro receives ultrasonic echoes from the transmitting and receiving beam direction for the ro reach the opening position of the specular reflection component from the puncture needle.

[0099](实施例2) [0099] (Example 2)

[0100] 根据本发明的实施例2的超声波诊断装置具有接收变迹功能,该接收变迹(apodization)功能被添加到实施例I的超声波诊断装置10的装置本体14的信号处理器44中。 [0100] apodization function having a receiving ultrasonic diagnostic apparatus of the present embodiment 2 according to the invention, the receiver apodization (apodization) function is added to the signal processor apparatus body ultrasonic diagnostic apparatus of Example I 10 14 44. 除了接收变迹功能外,本实施例的超声波诊断装置的配置与图I和2中的超声波诊断装置10实质上相同,并因此将不提供与图相结合的描述。 In addition to receiving apodization function, the ultrasonic diagnostic apparatus according to the present embodiment of the arrangement of FIG. I and the ultrasonic diagnostic apparatus 210 is substantially the same, and thus description will not be provided in conjunction with FIG. 下文中,在本实施例的超声波诊断装置的详细描述中,以相同的引用标号来表示与图2中示出的超声波诊断装置10的组件相同的那些组件。 Hereinafter, the detailed description of the ultrasonic diagnostic apparatus according to the present embodiment, the same reference numerals represent the same components as those components of the ultrasonic diagnostic apparatus shown in FIG. 2 10.

[0101] 接收变迹是在执行求和处理之前向多条接收数据给出加权因子的技术。 [0101] receiving apodization technique is given a weighting factor to the plurality of received data before summation process. 具体地,针对来自超声波束中心处的超声波换能器的接收信号设置最大的权重,以及随着到中心的距离增加,对接收信号设置越小的权重。 Specifically, the reception signal transducer for ultrasonic waves from the ultrasonic beam is provided at the center of the largest weight, and with increasing distance from the center, the received signal is provided to a smaller weight. 从而,有可能在对从所观察的目标直接到达的接收信号(其将在超声波束的中心处)加以突出的同时,执行接收处理,以使得接收到的超声波束可具有闻精度。 Thus, it is possible to receive a signal from the observed directly reach the target (which will be at the center of the ultrasonic beam) to be projected simultaneously, performs reception processing, so that the ultrasonic beam may have received audible accuracy.

[0102] 图7A是示出了发送和接收相关技术的超声波的方法的示意图,该方法由相关技术的超声波诊断装置执行。 [0102] FIG. 7A is a schematic diagram illustrating a method for transmitting and receiving ultrasonic waves related art, the method is performed by the ultrasonic diagnostic apparatus of the related art. 图7B是示出了本实施例的发送和接收超声波的方法示例的概要的示意图,该方法由本实施例的超声波诊断装置执行。 FIG 7B is a schematic diagram showing an outline of an example of a method of transmitting and receiving an ultrasonic wave according to the present embodiment, the ultrasonic diagnostic apparatus of this embodiment from the method of the present embodiment is performed. 图7A示出了相关技术的接收变迹的概要。 7A shows a related art receiving apodization summary. 通常将接收变迹的加权曲线W21的波峰与发送波束的中心位置C21设置为彼此一致。 Generally will receive apodization weighting curve peaks and the center position of the transmission beam W21 C21 is set to coincide with each other.

[0103] 图7B示出了本实施例的接收变迹的概要。 [0103] FIG 7B illustrates a schematic received apodization embodiment of the present embodiment. 从图7B中将会理解,在本实施例中,接收变迹的加权曲线W22具有两个波峰。 Will be understood from FIG. 7B, in the present embodiment, the receiving apodization weighting curve W22 has two peaks. 一个波峰被设置为与发送波束的中心位置C22—致,以及另一个波峰被设置在来自于穿刺针的镜面反射分量的中心位置C23处。 A peak is set to the center position of the transmission beam C22- actuator, and the other peaks are disposed in a central position C23 at the specular component from the puncture needle. 根据表达式 According to the expression

(I),将镜面反射分量的中心位置C23设置在与发送波束的中心位置C22相距Dltan2 0 I的位置处。 (I), the center position of the specular component C23 is provided at a center position of the transmission beam away Dltan2 0 I C22 position. 在由图2所示的装置本体14的信号处理器44所进行的接收聚焦处理中的附加处理之前,执行接收变迹处理。 Before the signal processor 14 receives the focus processing 44 performed by the apparatus body shown in FIG. 2 additional processing, performs reception processing apodization.

[0104] 通过这种方式,关于接收变迹的权重设置,设置了两个波峰,S卩,要突出接收信号的两个部位,由此获得具有高精度的对象组织的图像,并且还获得了高精度的穿刺针的图像。 [0104] In this way, on the reception weight setting apodization weights, it provided the two peaks, S Jie, to two projecting portions of the received signal, thereby obtaining an image of the target tissue with high accuracy, and also obtained the image of the puncture needle with high precision.

[0105] 如上所述,根据本实施例的超声波诊断装置,在发送波段中心位置和穿刺针上的镜面反射分量的到达位置处执行接收变迹。 [0105] As described above, the ultrasonic diagnostic apparatus according to the present embodiment, the specular component reaches a position on the transmission band and the center position of the puncture needle receiving apodization is performed. 因此,可能对这两个所观察的目标的接收信号执行突出处理,并且还提高了包括所插入的穿刺针在内的超声波图像的显示分辨率。 Thus, it is possible to perform projection processing these two reception signals observed object, and further comprising a display resolution increases the insertion puncture needle including the ultrasound image.

[0106] 虽然在本实施例中,已经描述了通过接收变迹,通过权重设置来设置两个波峰的模式,例如当没有向来自对象组织的普通超声回波信号(点反射分量)给出权重时,可以使用仅针对镜面反射分量设置波峰的模式。 [0106] In the present embodiment has been described by receiving apodization weight arranged to provide two peaks right mode, such as when no signal is given to the general ultrasonic echo (reflection point component) from the target tissue weight when, a peak may be used provided only for the specular component mode.

[0107] 在图7B中,已经描述了两个波峰在接收变迹的加权曲线W22中画出相同的正态曲线的模式。 [0107] In FIG. 7B, it has been described in the same two peaks shown in the normal curve of the weighting curve W22 received in the apodization pattern. 然而,也考虑对象组织和穿刺针之间加权曲线不同的情況,并因此可以将适合针的加权曲线应用到镜面反射分量。 However, also contemplated between the subject tissue and the needle different weighting curve, the weighting curve and thus can be applied to the needle for the specular component.

[0108] 虽然在图7B所示的实施例中使用了具有两个波峰的加权曲线W22,以实现针对发送波束中心位置与来自穿刺针的镜面反射分量到达的位置的接收变迹,本发明不限于此;为了实现针对单个位置的接收变迹,可以针对这些位置中的每ー个使用具有单个波峰的加权曲线。 [0108] Although the embodiment shown in FIG. 7B using the weighting curve W22 has two peaks, in order to achieve a position for the transmission beam reaches the center position of the specular reflection component from the puncture needle receiving apodization, the present invention does not limited thereto; in order to achieve a single position for receiving apodization can ー for each one of these positions weighting curve having a single peak.

[0109] 例如,图8中示出的实施例使用了具有单个波峰的加权曲线W23,该单个波峰被设置为与发送波束中心位置C22 —致,以实现发送波束中心位置的接收变迹,以及使用了具有单个波峰的加权曲线W24,该单个波峰被设置为与穿刺针反射的镜面反射分量的中心位置C23 —致,以实现针对穿刺针反射的镜面反射分量到达的位置的接收变迹。 [0109] For example, in FIG. 8 shows an embodiment using a weighting curve having a single peak W23 of, the single peak is set as the transmission beam center position C22 - activated to enable the reception apodization transmission beam center position, and using a weighting curve having a single peak W24, the single peak is set to the center position of the specular component reflected by the puncture needle C23 - induced to achieve apodization receiving specular reflection component for reflecting the puncture needle reaches the position.

[0110] 相应地,由于在本实施例中将包含来自对象组织的普通超声回波信号(下文中也称为对象组织分量)和来自穿刺针的镜面反射分量在内的接收信号存储在接收数据存储単元40中,信号处理器44针对所存储的相同接收数据实现了用于使用加权曲线W23来增强对象组织的接收变迹(对象组织增强处理),以及用于使用加权曲线W24增强来自穿刺针的镜面反射分量的接收变迹(镜面反射分量增强处理),并且图像处理器46合成単独增强的接收数据。 [0110] Accordingly, since the received data in the present embodiment comprises a common embodiment in the ultrasonic echo signal from the subject tissue (hereinafter also referred to as target tissue component) and the specular component from the puncture needle including the received signal storage radiolabeling storage unit 40, the signal processor 44 to achieve the same for the received data using the stored weighting curve W23 for enhancing receiving apodization target tissue (target tissue enhancement processing), and means for using the weighting curve W24 enhanced puncture needle from the specular component receiving apodization (specular component enhancement processing), and the image synthesis processor 46 receives data radiolabeling single enhanced. 可以在合成之前执行例如滤波处理的增强处理。 For example, enhancement processing can be performed prior to the synthesis filter processing. 从而,当重复使用存储在接收数据存储单元40中的相同接收数据时,使得用于对象组织分量和来自穿刺针的镜面反射分量的最优图像处理成为可能。 Thus, when used repeatedly stored in the received data storage unit 40 is the same as the received data, such that optimal image processing for the subject tissue component and the specular reflection component from the puncture needle is possible.

[0111] 用于接收变迹的加权曲线W23和W24是均具有展示出彼此类似的正态曲线的波峰的示例,然而本发明不限于此;如果所使用的加权曲线适于对象组织分量和来自穿刺针的镜面反射分量,波峰可以不同。 [0111] configured to receive apodization weighting curve W23 and W24 are similar to each other examples exhibit peak normal curve has, however, the present invention is not limited thereto; if the weighting curve used is adapted from the subject tissue component and specular component puncture needle, the peak may be different.

[0120](实施例4) [0120] (Example 4)

[0121] 根据本发明的实施例4的超声波诊断装置具有不同于增加到实施例I中描述的超声波诊断装置10的装置本体14的实施例3的开ロ合成功能。 [0121] The ultrasonic diagnostic apparatus having a different added as described in Example I Example Embodiment 14 of the apparatus body 10 open ro synthesis ultrasonic diagnostic apparatus 3 according to the present embodiment 4 according to the invention. 如上所述,与以上实施例3不同,根据本实施例的接收开ロ对应于以上实施例I的接收开ロ,针对一次发送,该接收开ロ被划分为:用于在发送波束方向上接收超声回波信号(点反射分量)的接收开ロ、以及用于由穿刺针反射的镜面反射分量到达的位置的接收开ロ。 As described above, different from the above embodiment 3, the receiving opening according to the present embodiment corresponds ro to ro Example I above embodiment receiving opening for a transmission, the receiver is divided into open ro: means for receiving the transmission beam direction receiving an ultrasonic echo signal (reflection point component) opening ro, and ro open position for receiving specular reflection component reflected by the arrival of the puncture needle. 因此,将省略类似的描述,并主要描述区別。 Therefore, a similar description will be omitted, and differences are mainly described.

[0122] 图10是示出了根据本实施例的发送和接收超声波的方法示例的概要的示意图,该方法由本实施例的超声波诊断装置执行。 [0122] FIG. 10 is a schematic diagram illustrating a method of transmitting and receiving an ultrasonic wave according to the present exemplary embodiment of the outline of the ultrasonic diagnostic apparatus of this embodiment from the method of the present embodiment is performed.

[0123] 本实施例中设置的接收开ロ是以发送方向为中心的接收开ロA,以及以用于镜面反射分量的超声波换能器为中心的接收开ロB,通过至少一个没有被用作接收开ロ的超声波换能器13,将接收开ロA和B彼此分开,这些接收开ロA和B均包括多个超声波换能器13。 [0123] ro receiving opening provided in the present embodiment is the embodiment of the transmission direction of the center receiving opening ro A, as well as the specular component for an ultrasonic transducer is a receiving opening center ro B, is not used by at least one ro opening for receiving an ultrasonic transducer 13, the reception on ro a and B separated from each other, the receivers a and B ro opening comprises a plurality of ultrasonic transducer 13.

[0124] 根据本实施例,发送开口和接收开ロA—致,以及从发送开ロ发送的超声波束被普通对象组织所反射,并作为普通超声回波信号(点反射分量)返回到接收开ロA,而镜面反射(镜像反射)中由穿刺针NI反射的镜面反射波(镜面反射分量)没有返回接收开ロA,而是返回接收开ロB。 [0124] According to the present embodiment, transmission and reception on ro A- opening actuator, and an ultrasonic beam transmitted from the transmitting ro opening is reflected by an ordinary subject tissue, and as an ordinary return ultrasonic echo signal (reflection point component) to the receiving opening ro a, and specular reflection (specular reflection component) the specular reflection (specular reflection) is reflected by the puncture needle does not return the received NI open ro a, but received back open ro B. 从而,在根据本实施例的超声波诊断装置中,接收开ロA可以接收到普通超声回波信号,以及接收开ロB可以接收到来自穿刺针NI的镜面反射分量。 Thus, in the ultrasonic diagnostic apparatus according to the present embodiment, the receiving opening can receive ro A normal ultrasonic echo signal, and a reception opening ro B may receive the specular reflection component from the puncture needle NI. 根据本实施例,发送开口和接收开ロA没有必要一致。 According to this embodiment, transmission and reception on ro opening A is not necessary the same.

[0125] 从而,根据本实施例,对两个接收开ロA和B接收到的超声回波信号进行合成,即,执行对接收开ロA和接收开ロB的开ロ合成处理,以合成对象组织BI和穿刺针NI的图像。 [0125] Thus, according to the present embodiment, the reception opening of the two A and B ro received ultrasound echo signals are synthesized, i.e., performs reception opening open ro ro synthetic process A and B of the receiving opening ro to synthesize target tissue image BI and the needle of NI.

[0126] 将没有被用作接收开ロ的超声波换能器13的至少ー个元素放置在接收开ロA和接收开ロB之间的原因是:为了确保接收到紧挨着普通图像信号强的发送开口下方的信号以及来自穿刺针的镜面反射分量强的信号,即使使用在接收电路中仅具有少量元素的便携式低成本类型,也将ー个接收开ロ与另ー个接收开ロ明显地分隔开。 [0126] will not be used as a receiving opening of the ultrasonic transducer ro ー least 13 disposed on the receiving element and the receiving opening A opening ro ro B is between reasons: to ensure that the received signal strength immediately ordinary image open downward transmission signal and the specular reflection from the puncture needle component signal intensity, even a low-cost portable type having only a small number of elements in the receiving circuit, also receiving opening ー ー reception with another ro ro obviously open separated.

[0127] 根据本发明,由于可以通过两个分开的接收开ロA和B来接收超声波束的一次发送中的普通超声回波信号和来自穿刺针NI的镜面反射分量,具有少量通道的装置也可以接收镜面反射分量。 [0127] According to the present invention, since A and B can start ro by two separate receiving ultrasonic echo signal received common transmission time of the ultrasonic beam and the specular reflection component from the puncture needle NI, the apparatus also having a small passage specular component may be received. 复用器36可以容易地进行在很多超声波换能器13上设置两个分开的接收开ロA和B。 The multiplexer 36 can be easily performed transducer disposed on two separate receiving opening 13 A and in many ultrasonic ro B.

[0128] 根据本实施例,通过将接收回波信号作为接收数据(单个超声波换能器13接收到的接收数据,下面可以将其简称为元素数据)临时存储在接收数据存储单元40中,在一次发送中根据元素数据在两个或更多方向(包括发送波束方向和穿刺针镜面反射方向)上执行接收波束成形,以及合成并显示这些超声回波信号数据的数据,可以在不降低帧速率的情况下提供具有增强的穿刺针可见度的图像,当插入穿刺针时,这是重要的。 [0128] According to the present embodiment, as the echo signals received by the (single data element of the ultrasonic transducer 13 receives the received data, it may be referred to below) temporarily stores the received data in the received data storage unit 40, in a transmission element according to the data in two or more directions (including the puncture needle and the direction of the transmission beam direction of specular reflection) performs beamforming on the received and these data are synthesized and displayed ultrasonic echo signal data, the frame rate may be reduced without providing an image having enhanced visibility of the puncture needle in the case, when the insertion puncture needle, which is important.

[0129] 从而,根据以上实施例3,执行了多次超声波束发送处理,并且针对每个所发送的超声波束执行开ロ合成处理,由此,普通的超声回波信号(点反射分量)和来自穿刺针NI的镜面反射分量被多个不同的开ロ所接收到并进行合成。 [0129] Thus, according to Example 3 above, an ultrasonic beam is performed multiple transmission process, and performs an ultrasonic beam transmitted for each open ro synthesis process, whereby, Common ultrasonic echo signal (reflection point component) and specular reflection component from the puncture needle NI are received by a plurality of different opening and synthesized to ro. 根据本实施例,另ー方面,接收开ロA和接收开ロB可以在一次发送中接收在发送波束方向上和穿刺针镜面反射方向上的回波信号,以使得与以上实施例3相比,不降低帧速率,其中,在多次发送中,接收开ロI和接收开ロ2分别接收在发送波束方向上和穿刺针镜面反射方向上的回波信号,以及此外,没有必要如以上在实施例3中所要求的,通过复用器36在发送开口和接收开ロI与发送开ロ和接收开ロ2之间切換,由此通过复用器36实现了从发送开ロ到两个接收开ロA和B的容易且快速的切換。 3 embodiment, compared to the present embodiment, ー another aspect, the receiving opening receiving opening ro ro A and B can be received in the beam direction and the echo signal transmitted on the specular reflection direction of the puncture needle, such that the above embodiment in accordance with a transmission without reducing the frame rate, wherein, in multiple transmission, reception on the reception opening ro ro I and 2 receive in the beam direction and the echo signal transmitted on the specular reflection direction of the puncture needle, and moreover, it is not necessary as described above in in Example 3 required by the multiplexer 36 and the transmit aperture receiving opening open ro ro I transmission and reception switching between open ro 2, thereby achieving ro from two transmitted through a multiplexer 36 to open ro receiving a and B opened easily and fast switching. 从而,可以消除在以上实施例3中很可能发生的诸如切换时间中的延迟之类的问题。 Thus, problems such as a delay such switching time in Example 3 is likely to occur in the above embodiment can be eliminated.

[0130] 此外,根据本实施例,由于在开ロ合成处理中合并了接收开ロA的元素数据和接收开ロB的元素数据,由此增加了具有所插入的穿刺针的超声波图像的显示分辨率,其中,在接收开ロA的元素数据中,来自对象组织BI的普通超声回波信号(点反射分量)占主导,在接收开ロB的元素数据中,来自穿刺针NI的镜面反射分量占主导。 [0130] Further, according to the present embodiment, since the data elements merged ro receiving opening and received in the opening A synthesis process ro ro opening element data B, thereby increasing the ultrasonic image having the inserted puncture needle resolution, wherein the data element a in the receiving opening ro ordinary ultrasonic echo signal from the subject tissue BI (point reflection component) is dominant in the data receiving element to open ro B, the specular reflection from the puncture needle NI component is dominant.

[0131](实施例5) [0131] (Example 5)

[0132] 根据本发明的实施例5的超声波诊断装置与实施例I的超声波诊断装置10的不同之处在于,探头12具有发送具有偏转角度的超声波束,而不是在与超声波换能器13的阵列方向垂直的方向上发送超声波束的功能(參见图11)。 [0132] 10 differs from the embodiment in that the ultrasonic diagnostic apparatus of the embodiment 5 according to the present invention, the ultrasonic diagnostic apparatus of Example I, having a probe 12 transmits an ultrasonic beam having the deflection angle, rather than the ultrasonic transducer 13 a function of transmitting an ultrasonic beam in a direction perpendicular to the array direction (see FIG. 11). 除此之外,本实施例的超声波诊断装置与图I和2中的超声波诊断装置10实质上相同,且因此将不提供与图相结合的描述。 In addition, the ultrasonic diagnostic apparatus of Fig. I and 2 of the ultrasonic diagnostic apparatus 10 of the present embodiment are substantially the same, and thus the description will not be provided in conjunction with FIG. 本实施例的超声波诊断装置的装置本体具有与该新颖功能相对应的配置。 The ultrasonic diagnostic apparatus main body unit according to the present embodiment has a configuration corresponding to the new function. 下文中,在本实施例的超声波诊断装置的详细描述中,以相同的引用标号来表示与图2中示出的超声波诊断装置10的组件相同的那些组件。 Hereinafter, the detailed description of the ultrasonic diagnostic apparatus according to the present embodiment, the same reference numerals represent the same components as those components of the ultrasonic diagnostic apparatus shown in FIG. 2 10.

[0133] 图11是示出了预测范围的方法示例的示意图,在以偏转角发送的超声波束中,来自穿刺针的超声波的镜面反射波(镜面反射分量)在该范围中到达。 [0133] FIG. 11 is a schematic diagram showing an example of a method of prediction range, the deflection angle of the ultrasonic beam to be transmitted, the specular reflection from the ultrasonic wave puncture needle (specular reflection component) reaches this range.

[0134] 如果穿刺针NI进入对象BI的插入角度是0 2,当以倾角小2从超声波的进入位置P41进入的超声波在穿刺针NI上导致在深度D2处的镜面反射之后,从对象BI发射反射波的点是P41',以及从超声波的进入位置P41到穿刺针NI的插入位置之间的距离是W2,反射波返回的点P41'与进入点P41之间的距离L2由表达式(3)来计算。 [0134] If the needle NI entry target BI insertion angle is 02, when a small tilt angle 2 enters from the entry position P41 ultrasound ultrasound results in the puncture needle NI after specular reflection depth D2 at emitted from the object BI point of the reflected wave is P41 ', and W2 is the distance from the insertion position into the position of the ultrasonic wave to the puncture needle NI P41 reflected waves returning point P41' enters the distance L2 between the point P41 by expression (3 ) is calculated.

[0135] 相应地,在本实施例的超声波诊断装置中,优选考虑到反射波返回的点P41'来确定接收开ロ的宽度。 [0135] Accordingly, the ultrasonic diagnostic apparatus in the present embodiment, it is preferable to consider the return of the reflected wave point P41 'received to determine the width of the opening ro.

[0139] 如上所述,根据本实施例的超声波诊断装置和装置本体,即使当以倾角从超声波探头发送超声波束时,也可能基于穿刺针和超声波探头之间的位置关系来确定接收开ロ的位置和宽度(通道数目)。 [0139] As described above, the ultrasonic diagnostic apparatus and the apparatus body according to the present embodiment, even when the inclination angle from the ultrasonic probe transmit an ultrasonic beam, it is possible to determine the position of the receiving opening ro relationship between the puncture needle and the ultrasound probe based on position and the width (number of channels). 因此,可能提高包括所插入的穿刺针在内的超声波图像的分辨率,由此提闻穿刺针的可见度。 Thus, improving the resolution may include the insertion puncture needle including an ultrasound image, thereby improving the visibility of the puncture needle of smell.
